SAFETY TIPSSafe Handling of Glassware
With the amount of glassware used in laboratories today, in various laboratory operations, chances are good that an accident will result in cuts, slashes, or slices. Minor cuts are the most frequent result of laboratory glassware accidents. However more serious accidents could result with flying glass, exposure to chemicals, or fires. Remember, each piece of glassware is designed for a specific purpose and it should only be used for that purpose.
